3G/4G WAN Connectivity

The FortiGate 40F Series includes a USB port that allows you to plug in a compatible third-party 3G/4G USB modem, providing additional WAN connectivity or a redundant link for maximum reliability.

Compact and Reliable Form Factor

Designed for small environments, you can place it on a desktop or wall-mount it. It is small, lightweight yet highly reliable with
a superior MTBF (Mean Time Between Failure), minimizing the chance of a network disruption.

FortiLink protocol enables you to converge security and the network access by integrating the FortiSwitch into the FortiGate as a logical extension of the NGFW. These FortiLink enabled ports can be reconfigured as regular ports as needed.

Fortinet Security Fabric

Security Fabric

The Security Fabric is the cybersecurity platform that enables digital innovations. It delivers broad visibility of the entire attack surface to better manage risk. Its unified and integrated solution reduces the complexity of supporting multiple-point products, while automated workflows increase operational speeds and reduce response times across the Fortinet deployment ecosystem. The Fortinet Security Fabric overs the following key areas under a single management center:

  • Security-Driven Networking that secures, accelerates, and unifies the network and user experience
  • Zero Trust Network Access that identifies and secures users and devices in real-time, on and off of the network
  • Dynamic Cloud Security that protects and controls cloud infrastructures and applications
  • AI-Driven Security Operations that automatically prevents, detects, isolates, and responds to cyber threats


FortiGates are the foundation of the Fortinet Security Fabric—the core is FortiOS. All security and networking capabilities across the entire FortiGate platform are controlled with one intuitive operating system. FortiOS reduces complexity, costs, and response times by truly consolidating next-generation security products and services into one platform.

  • A truly consolidated platform with a single OS and pane-of-glass across the entire digital attack surface
  • Industry-leading protection: NSS Labs Recommended, VB100, AV Comparatives, and ICSA validated security and performance
  • Leverage the latest technologies such as deception-based security
  • Control thousands of applications, block the latest exploits, and filter web traffic based on millions of real-time URL ratings in addition to true TLS 1.3 support
  • Automatically prevent, detect, and mitigate advanced attacks within minutes with an integrated AI-driven security and advanced threat protection
  • Improve and unify the user experience with innovative SD-WAN capabilities with the ability to detect, contain, and isolate threats with automated segmentation
